The USB Promoter Group has announced the USB4 specification

The USB Promoter Group has announced the USB4 specification and that the new standard will be released soon. It is based on Intel's Thunderbolt protocol and enables multiple simultaneous data and display protocols. It also doubles the transfer rates from USB 3.2's 20 Gbps to 40 Gbps (over 40 Gbps-certified cables). The new interface will use USB Type-C connectors and will be compatible with existing USB 3.2, USB 2.0 and Thunderbolt 3 hosts and devices. The complete USB4 specification will be released in the second half of 2019.

"The primary goal of USB is to deliver the best user experience combining data, display and power delivery over a user-friendly and robust cable and connector solution,” said Brad Saunders, USB Promoter Group Chairman. "The USB4 solution specifically tailors bus operation to further enhance this experience by optimizing the blend of data and display over a single connection and enabling the further doubling of performance."

"Releasing the Thunderbolt protocol specification is a significant milestone for making today’s simplest and most versatile port available to everyone," said Jason Ziller, General Manager, Client Connectivity Division at Intel. "By collaborating with the USB Promoter Group, we’re opening the doors for innovation across a wide range of devices and increasing compatibility to deliver better experiences to consumers."Источник
